摘要

The arrangement (10) has a cooling device thermally coupled with an LED unit (8), and including a cooling duct (6) for flow of a cooling medium and for evacuation of heat lost from the LED unit. Turbojets (12a, 12b) are provided for conveying the cooling medium through the cooling duct that is arranged in the LED unit. A ventilator e.g. axial ventilator or radial ventilator, and the turbojets are arranged in the cooling duct. A venture tube is formed in a solid cooling body that is made of metal.
